T0 LLM ill/2,0m, t muy conce/"11,:

Be it known that I, ORLA H. 11min, a citi zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventedcertain' new and useful lmprovements in Automatic IllVindows, of 'which the following isv aspeci'lication.

This invention relates to improvements in iireproofivindows of that type which is arranged t`o close and be locked automatically in the presence of fire',` and the invention is concerned more particularly with certain iinproved sash-locking devices which. are admirably adapted for the automatic iireproo'f Windows.

It has been observed that when a ireproof vwindow is subjected to intense heat, as iii a hre, the distortion and 'warping are so` great that ordinary catches or the like c annot y safely be relied upon to hold the window closed. Moreover, such Windows are in case oi' lire subjected to the action of streams of Water from hose, andwhere the locking mechanism is exposed it is liable to be released by the impact .of the Water'.

The salient objects of my invention areto provide an automatic sash-locking mechanism 'Which is very strong and which cannot be rendered inoperative nor thrown out by distortion of the lsash or 'sash-frame and Which will tol a great degree prevent such distortion; to provide an automatic sash-lock ing device 'whicl'i is conceal'edand protected, yet readily accessible for inspection or re' air, and to provide an automatic sash-loclking mechanisniwliich will act upon the iull length tion of the samein the hollow lower sash-rail or elsewhere.-

To the. above ends my invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims.

The inventionin a preferred forin'will Specification of Letters-Peanut.

more readily u-nderstood. by reference to the accompanying drawings, in which- Figure' l is a broken-away inside elevation of anautoniatic iireprooi sash providedwith my improvements, the sash being closed. Fig. 2 is a vertical sect-ion of the same, show'- ing the sash in open position. Fig. 3 is `an venlarged broken-out vertical section oi' the Patented March 19,1907..

sash in closedrposition and locked'. ,-Fig. 4 is a detail view oi" one of the sash-pivots, show'- ing the open position of the sashin dotted lines. 111g., 5 is an enlarged cross-section taken on line` V V of Fig. 1. Fig. 6 is a detail detail view of the unlocking-lever and its bracket.

The window-frame, comprising the lintel 1 the uprights 2, and the sill 25, is made, as

usual in liireproor` windows, of sheet metal formed up to provide a hollow casing whereV of the several side and end members are riveted or otherwise suitably united to prevent i 'separation of said parts by intense heat.

The sectional Jform ofthe sill 3 and of th lint'el l are' clearly shown in Fig. 3; drawing. rectangular iii section; but' its lower wall is. formed with an inclined portion l', the :upper edge o'f which is recessed intoihe lintel and rl`he .lintel' is, roughly-speaking the lower edge ci which projects. a little bclcw' the same. Ai'ljacent the inner and upper edge oi sind inclined portion-is' a depend-V ing lip'l, formed with a harige 5. l Adjacent the outer face of' th( iiiitel,but set back `to or hush wit-li` the' outer plane oi the sash, is a similar depending lip 6,'

art of, the locking device is-inclosed. The hp 6 is 'provided willi a weather-flange 6', which is out.- wardly and theninwardly turned.

made immovable and is vso shown.

prises .the upper rail S, the stilcs Q, and the which forms the out-cr wall of: a recessdiy which a 9o lower rail. l0 andis fitted with the usual rire-'f proofglass ll, asis thellowcrsash 7. The .I

sash 11 is of hollow sheet-metal construction, and the glass is attached or mounted in any well-known n'anner. The window is swing' ably mounted by means of brackets l2, se-l cured to the stilcs 9, and attached by pivot- 65 view showing several of the drip-water outn lets at the bottom of the sash, and Fig.I 7 is a Afor brackets 14 and 12.

bolts 13 to stationary brackets 14, which are screwed to the inner faces of the frame sides 2. Reinforcing-plates15 should be provided The brackets 12 are formed with inwardly-projecting ears 12 whereby the pivots 13 are so positioned that the sash will be self-closing by gravity. Pref ably said brackets are placed midway betw n the ends of the sash. It will be observed in Figs. 2and 4 that the upper end of each lixed bracket 14 is formed with an inclined face 14, set at aA roper angleand forming a positive stop for imiting the opening of the sash. By this neat Aand effective ldevice I dispense with limit-chains or4 the 1 e.

Both the upper and the lower rail of the sash 11 are provided with my improvedlocking devces, which are pactically identical in construction. The upper one, thereof is housed by the lintel, .while lthe lower one/is carried by the bottom sash-rail 10. The lock for the upper end of the sash is constructed as follows: The top of the upper sash-rail 8 is rovided with a strong longitudinal upwar lyrojecting. flange 16, ,which extends the ful width of the sash, or n early so,

. and may be termed -a .`stop or locking flange.

supporting the latter.

Pivoted within the recess of the lintel is a transverse lockingbar 1 7, coextensive in length with said flange 16 and arywhen the sash is closed, therebylocking the sash in closed position, .as shown in Fig. 3. The pivoting of the locking-bar is. preferably upon a row of eyebolt-s 18 or their equivalent, the eyes of which loosely engage round holes throughthe upper edge of'said bar, thereby The eyebolts 18 are secured to. the inner lip 5 of the lintel 1. When thesash i's being closed and nearsthat osition, its locking-flange 16 lifts and passes beneath the locking bar 17-, which then4 drops as aforesaid. The locking device for the lower endof the sash is very similar and 'comprises a locking-bar'lQ, pivozed on eyebolts 20, and an hupwardly-projecting flange 21, adapted to be engaged by said bar 1 9. Flangel 21 is formed on or held by the meeting-rail7 of the lower sash 7. Said bar and flange both extend the length of the sashrail.I In this case the eyebolts 2C' are secured to the inner face of the upper meeting-rail 10; The bottom 22 of therail 10 is inclined, as shown, and forms a stop for said lockingbar when the latter is raised to permif. opening of the sash 11.'

'Any suitable meansfor unlocking the window maybe employed, thatshown in the drawingbeing deemed the most suitable for coperationwith my loekingdevices. For lifting the top locking-bar 17 I provide a lever 23, pivoted on a bracket 2:4, secured to the inner sideiof the top sash-rail. ver passes through' a slot in .the sash-rail and' 'of the lower sash.

, in the presence of -lire and water.

'3. The lever-bracket 24 is constructed to form a stop as well as a pivot for said lever. Attached to the external end ol-` said lever is a smooth .metal ring or pulley 25, through which passes a cord or wire 26, the respccl tive ends of lwhich are. attached to an operating-chain 2.7 and a metal strip or wire 28, the -latter through the intermediacy of a fusible link 29. rlhe member 2S passes through openings cut in the llower sash-rail 10 and is attached to an eye 3() on the lower locking-bar i For engaging' the operati!ig-ehain 27 a catch or hook 31 is provided upon the rail 7 open at an desired angle within its limits by engaging the chain 27 with the catch device 31. In case of fire or a' degree of heat snllcient to separate the fuse-link 29 the sash will obviously swing shut by gravity and will be solidly locked by thetwo gravitydiars 17 and 19. inthe closing' movement of the sash its locking-flange lwill slidingly. lift the upper locking-bar, while its lower lockingbar will pass over the ,lower locking-innige 21. As they drop the locking-bars are sulliciently heavy to return'the lever 23. and to draw the cord 26 a short. distance'through the ring 25 on said lever. ranged tol fall by gravity behind the latter The sash may be opened by .pulling down on the chain 27, which movement will trip the lever 23, lift locking-bar 17, and also draw up wire 28 and locking-bar 1Q. 'lhe sash is now freed, and further actuation of cha-in 27 will pull the top of the. sash inwardly. lThe chain may then bel'astcned as aforesaid.

rPhe u per sash-rail S 1s provided with a groove-s iapedinner flange 32, which takes over4 the lintel-flange 5', and withan outer flange 33, which takes vinto the. grooved weather-fiange 64. Similarlyr the lower sashrail 10 is provided 'with flanges 34 and 35, which respectively take over the'plain llange 36 and into the grooved llange 37 on the rail 7 of the lower sash. All of said flanges forni the sash-stops in one direction, while the locking-bars, together with the strong rigid llanges 16 and 21., form equally positive stops in the otherdirection.

l .lt is to bc particularly noted that the sashlockingdevices act upon the full lneadth-of the sash at both top and bottom. This construction will prevent distortion of the sash The construction has the further advantage of being self-contained when the sash is in its normale., closed-position. It is thus well protected from the ele,A .ents and presents no unsightly parts. The certainty of operation wil-l be evident when vthe simplicitv of the mechanism is considered.'

vIn cold weather if the air inside the build- IIO -inner 'face of. the pane 11 andl'will run down. over the lower sashrail,'.the flange 34, and the top of the meeting-rail 7'; 10 revent ing is heated', and especially When the xi/'ins' dou-W is closed, Water will conden'se upon the the accumulation of such water Wit iin the trough formed by; the iiange 21', -I cut through :said flange 'a series of'openings 38, as showny in Fig. 6. The Swater Will run through these openings .and Willdrip' from flange. '36 toiiange 35, from whichit Will either ,evaporate 'or will fall to the ground.
